Newport, Rhode Island, USA - The Editorial Staff

There’s plenty of news to report starting with MIRACLE Systems announcement that the
software for the QXL is near completion. Now any PC can Multi-Task, provided it has a
QXL installed.

The PROGS from Belgium report that the latest versions of LINEDESIGN and
DATADESIGN operate perfectly with any QL and compatible configuration. Both
programs have had major improvements (new features) added as well. PD software
authors will be happy to know that DATADESIGN contains a demo version of
ENGINE REXT, which can be FREELY used in PD programs (the implement
command is disabled).

Davide Santachiara of ERGON DEVELOPMENT, Italy reports two new software
packages, the first being "ZM /128" an addition to their stable of Spectrum emulators, the
ZM/128 supports emulation of Spectrum 128K machines. Their second release is titled
"ERGON FLOPPY DISK UTILITIES’, a package of useful tools for ALL density disk
drives including HD and ED. Davide informed us that while Ergon cannot accept credit
cards, they can accept Direct Bank Transfers. Send Bank Transfers to:

BANCA POPOLARE DELL’ EMILIA ITALY
SWIFT BPMOD2 - TELEX 510031 emipop
SEDE REGGIO EMILIA - CC 6533/73 - DAVIDE SANTACHIARA

Davide reminds us to include 10,000 ITL to cover bank transfer fees (the fee is the same
for any currency).

Tony Firshman of TF SERVICES in the UK is shipping the long awaited Minerva 1.97
ROM upgrade. Tony also reports that Minerva MK II is now equipped with improved
battery connections and a D9 connector support his new ANALOGUE and PARALLEL
interfaces used with the I2C bus.

Bill Richardson of W. N. RICHARDSON & CO. (EEC) reports that he's shipping new
KEYBOARD MEMBRANES. (Editor's Note: Bill deserves the thanks of all QL'ers for
single handedly restarting production of Keyboard membranes, the original stock had
dwindled down to nothing.)

MIRACLE SYSTEMS will sponsor a QL show on Saturday, the 17 July 1993 at the
EUROVOLLEY CENTRE, Beneluxlaan, Vilvoorde, BRUSSELS, BELGIUM. The
main attraction will be the QXL in operation. Entry to the show is FREE.

The German Post Office is undertaking a countywide change in "POST CODES"
effective 1 July 1993. We've received the new codes for Jochen Merz (D-47169) and
Jurgen Falkenberg (D-75236), we'll report others as they become available.

QUANTA has released three new additions disks. The new disks include DEMO 5 and
the new LIBGUIDE (now loads directly from boot). The following seven disks have
been affected by either additions or upgrades:

SOFTWARE 87 of the UK, has a new software inquiry telephone number (GB) 071 285
9008. You can reach them on weekdays between the hours of 1400 to 1700 GMT.

We (IQLR) have recently installed a FAX machine. You can now reach us by either
voice or fax at (USA) 401 848 3805.

Jurgen Falkenberg of Germany has sent preliminary product information on a new
product entitled the "QL-IFO-CARD". Billed as an intelligent I/O card with powerful
abilities for input and output It is reported to be compatible with any QL system
including the Gold-Card.

Now to the hard part (it's difficult to write about an affair you were so closely connected
with) IQLR sponsored the first ever QL (only) get-together in North America on the 5th
of June 1993. The affair was organized and held within a seven week time span. Even
with such short notice, 60 QL'ers managed to change their schedules and attend. The
average attendee traveled over 800 miles with Claude A. J. Schleyer from Albuquerque,
New Mexico traveling the greatest distance (2800 miles each direction), our publisher
traveled the shortest distance (2 miles).

Those attending from the UK included Stuart Honeyball of MIRACLE SYSTEMS who
demonstrated the QXL card on our editors 386DX PC. Tony Firshman of
TF SERVICES demonstrated the new Minerva 1.97, HERMES (replacement for the
8049 co-processor), and his new ANALOGUE and PARALLEL interfaces for use with
Minerva MK II's I2C bus. Bill Richardson of W. N. RICHARDSON & CO. was busy
selling KEYBOARD-90 and HARDDISK interfaces from Jurgen Falkenberg, and was
doing a brisk business with new QL Keyboard Membranes.

From Toronto CANADA came Hugh Howie who demonstrated PD software from the
Toronto user group, gave away samples of the group's newsletter, and recruited new
members.

Representatives from the USA included Bill Cable of WOOD & WIND COMPUTING
who demonstrated his new super financial package "ΟΙ ΕΕΚ". Tim Swenson of
"QL HACKER'S JOURNAL" fame offering disk collections of his fine publication as
well as great looking T-Shirts. Frank Davis and Paul Holmgren of
MECHANICAL AFFINITY and UPDATE MAGAZINE offered a complete line of QL
hardware and software from the major suppliers worldwide. Frank also offered back
issues of his quarterly UPDATE magazine. SeaCoast Services had Collector’s Editions of
IQLR and special "MIRACLE in NEWPORT" T-Shirts.

John Impellizzeri and Don Walterman from the Detroit, Michigan area demonstrated
differently configured QL systems including an assembled QL-2000 Tower Cased QL
from Jurgen Falkenberg. While John and Don were not selling anything their table was
quite busy.

A big part of "MIRACLE in NEWPORT" was the opportunity (many QL'ers took
advantage of) to socialize and pick one-anothers brains, while gleening as much as
possible from our UK visitors. Information flowed like a river at crest. On Sunday the
6th of June many of us gathered at the Pinapple Motel where Tony Firshman and Don

EDITORIAL - (CONT’D)

Walterman demonstrated how a Bulletin Board operates using QBOX software. Stuart
Honeyball was fascinated by a demonstration of RANDOM DOT STEROGRAMS by
Herb Schaaf of the CATS group. (Editor's Note: look for Herb's RDS in this issue.)

It's nearly impossible to name all those who attended and helped make "MIRACLE in
NEWPORT" the success it was, but in particular we would like to single out three user
groups who were very well represented; CATS from the Washington DC area, LIST from
the New York-Long Island area, and NESQLUG from the Boston area.

Our SPECIAL THANKS go to the NESQLUG group who provided and served
refreshments that made even the "Coffee Break" an event to remember.

Rather than continue on and on we'll let others write about "MIRACLE in NEWPORT".
Included in this issue is a pictorial view of the get-to-gether, hoping the old addage of a
picture being worth a thousand words is true.

So many of our readers have either called or wrote expressing regrets on not being able
to attend on such short notice. The response to "MIRACLE in NEWPORT" was so
overwhelming that we're already talking about next year and hope to have more
information available by the end of the year. At present we are looking at mid-May 1994

with the location being either INDIANA, the WASHINGTON DC area, or again in
NEWPORT.

MIRACLE in NEWPORT - AN ENGLISHMAN’S VIEW
London, GREAT BRITAIN - Tony Firshman (TF SERVICES)

When I heard that Bob Dyl was organising a QL event in Newport, it seemed heaven
sent, as I had just given up in the infamous free’ Hoover tickets! (Editor's Note: Hoover
had a promotion that offered free airline tickets if you purchased one of their appliances,
it ended up badly.) There also appeared to be a cut-price ticket war going on at the same
time. So when Stuart Honeyball (Miracle Systems) said how about going, what other
answer could I give.

We both booked with Virgin Atlantic (of course), and decided to come for five days so
we could see more than just the show.

This was the first trip for both of us, and I certainly had many pre-conceived ideas about
the 'states' We were met by Dick Taylor and Bob Dyl at the International Airport in
Boston, and left in the middle of rush hour traffic. Almost the first experience was the
sound of a thin guy in a vast truck yelling "out of the way a***ole" to two nice old ladies
in an enormous car. We were then stuck in a noisy underground Boston traffic jam. It
seemed my notions of the states were to be proved right

HOW WRONG I WAS. Once we arrived in Newport, the politeness and friendliness of
everyone was quite incredible. We were completely thrown by a very effusive welcome
by a hotel receptionist, as if we were old friends. "You must think we're someone else’ we
said dumbfounded. A very civilised and educated barman took a great deal of trouble
directing us to a place to eat. Traffic stopped to wave us rare pedestrians across the road.
Cars passed well over to the left while we were cycling. Cars drove slowly. The air was
clean. "Nice to hear voices from the old country' from a stranger on the train. All the
(wooden) houses appeared to have acres of ground, no fences, and were very
picturesque... and so on.

It was a great shock to return to the old smelly noisy rude London in a heat wave, it made
me feel чег glad that I'm moving out in six weeks to a more civilised Ascot. I guess New
York would be something else, but we do not hear about the civilised USA we found in
Newport.

We had a great holiday, and saw a great deal of Newport and the surrounding area, we
even had the oppotunity to visit Cape Cod (our thanks to Sherm Waterman for his guided
tour). We ate plentiful and very cheaply, and drank a great deal of Bud Lite!

Oh yes - the show! Bob was clearly quite concerned that everything would happen and
people would come on the day - he had nothing to worry about. He produced very
professional price lists and special T-Shirts for us all, and over 55 people turned up.

Stuart Honeyball started sales of the QXL card for the PC. Software for it arrived hot
from Tony Tebby in France via modem and it was quite something to see the familiar old
QL mode 4 screens on Dick Taylor’s modern PC. This card gives a QL with up to 8mb of
ram and is at least 5 times faster than a QL with Gold Card.

Bill Richardson (EEC) who arrived a few days earlier than we did, was selling his usual
range of hardware, including Faulkenberg harddick and keyboard interfaces. Bill also
announced that he had negotiated the restart of production of QL keyboard membranes.

M. I. N. - ΑΝ ENGLISHMAN’S VIEW - (CONT'D)

Tony Firshman (me) using yet another machine loaned by Dick Taylor, launched version
1.97 of the Minerva ROM which now has built-in multibasic. It allows (with Hermes)
split output and input baud rates for use with serial mouse (from EEC), and for the first
time anywhere, we showed our analogue and parallel interfaces for use with the MK II
Minerva’s I2C bus. Also on display and selling well was Hermes, the working IPC that
replaces the QL’s bugged 8049. It allows reliable serial transfers up to 19200 bps and
eliminates keybounce.

There were also traders from the states. My apologies for not mentioning them by name
but we were so busy all day that I didn’t have a chance to follow their dealings!

It was a very worthwhile trip in many ways, for us old country types. Both Bob and Dick
spent most of their time, it seemed, ferrying us about. We will certainly visit again and
cannot thank our American friends too much for their welcome.

REVIEW OF IMAGE PROCESSOR 2 DILWYN JONES COMPUTING
Shelby Township, Michigan, USA - John J. Impellizzeri

Image Processor 2 from Dilwyn Jones Computing is a powerful program to aid in editing
or creating QL screen pictures. It includes handy and powerful utilities such as
converting from one screen mode to another, removing color, changing one color to
another, adding text, enhancing images, block and window handling and the ability to
zoom in on and edit a specific part of a screen.

Image Processor (IP) needs a QL with at least 512K of RAM and a floppy drive. It will
work with or without a Gold Card. No toolkit extras are needed, however it can use the
Toolkit 2 defaults if you have TK2. IP comes with an excellent 28 page manual. This
manual states that the program will work on JM, JS and Minerva 1.92 ROM's. I can
report that it also works on an MG ROM and Minerva 1.97. IP is a Qliberator compiled
program. The disk includes the needed runtime extensions if you don't have them loaded
already, and multitasks well All functions can be accessed from the keyboard, although
a joystick or mouse can be used.

IP has a built in help facility to assist the user. Just press F1 and up pops a help screen
with text pertaining to the function you just selected. This works similar to the help in
the Psion software; if you ask for help at the main menu, it offers a list of the available
functions, if you ask for help after selecting a function it gives specific assistance for that
function. The help is also configurable. As delivered, whenever you select an item from
the menu, a help screen will appear to guide you. This is handy when you are first
learning the program. Once you are familiar with the program, this gets annoying and
slows you down, so IP allows you to turn off this automatic help. Help is still available if
you need it. While this online assistance is great, it doesn't replace the manual. I would
still recommend reading the manual to get a feel for all IP can do.

I mentioned that the help was configurable. Many parts of IP are configurable. After
you've used the program awhile and find your always changing IP's built in defaults, you
can configure the program so it starts up just the way you want it.

A very nice part of IP is that if you use any function that would permanently alter the
screen, the change is made on a temporary basis and you are given the chance to see how
it looks and a choice to keep it or go back to what you had. This is very good in case you
make an ’oops’. It's still a wise idea to save your work in progress regularly and maybe
keep a few older versions just in case.

Memory permitting, you can have up to 9 screens loaded at once and can easily switch
between them. IP allows you to copy screens, merge them, or do cut & paste type block
moves between screens.

All of IP's functions can be used in either of the QL's screen modes. IP can also convert
a screen from one mode to the other. Depending on the picture this sometimes looks OK
and sometimes it doesn’t. However with all of the editing functions available it can be
made to look reasonable if you have to have a screen in a specific mode. IP also lets you
switch the screen mode without changing the picture. There is an Unflash function to
tidy things up if you load a mode 4 screen with the QL in mode 8. The program can save
and load standard QL screen files. In addition, it can save and load compressed screens in
its own format and one compatible with The Painter and The Clipart programs from
PROGS. It can also load compressed screens from Digital Precision's Eye-Q.

IMAGE PROCESSOR 2 - (CONT'D)

No screen image utility would be complete without text and graphics drawing facilities.
IP has both, allowing many types of graphic shapes such as circles, rectangles, arcs,
polygons and lines to be 'drawn' on the screen, moved around, and sizes & colors
changed. Shapes can be filled with a color, and there is a paint brush option with an
adjustable size brush to paint an area free hand. A ’spray’ function is also available to
tone an area with a color similar to using an airbrush. You can specify the size of the
area, the color, and the density. Text can be added anywhere. Many options exist for
text. Various sizes, ink and paper colors, and fonts can be used. IP comes with 22 fonts
on disk and it can use almost any standard QL font from other packages like Lightning or
desktop publishing programs. A handy feature is the ability to specify the OVER value.
This works like the OVER function in SuperBASIC. It determines whether text entered
will be placed using the ink and paper colors, or superimposed or blended in to the
image. Experimentation is best here to see the different effects, and this is easy and
painless with IP's confirmation option.

I've left a few of IP's most powerful functions for last. Enhance will attempt to clean up
any graininess or random dots in a picture. The manual states that it is best used on a
digitized picture to clean up any noise signals introduced during the digitization. 1t also
says it is not too effective on hand drawn, dark, or smoothly colored pictures. Like most
of the other functions it has an undo option so experimentation is worth a try. If the
result doesn't please you it'S easy to undo. Outline will generate a white on black
cartoon-like outline of a picture. It works best if there are only solid colors in the picture.
Stippled colors can confuse it. Since it also has an undo option, it won't hurt to try it and
if it doesn't give the results you want, you can always undo it and re-edit the picture and
try again. Both enhance and outline work quite fast considering what they accomplish.
The content of the picture does seem to have an affect on the speed, but each function
took less than 20 seconds to do the whole screen on a Gold Card machine.

IP has a windowing facility. This lets you process only a portion of a screen leaving the
rest of it untouched. The size of the window is adjustable from practically pixel size up to
the size of the screen. Almost all of IP's functions are available in this facility in addition
to a few new ones. You can decolor, recolor, outline, enhance, mirror the image
vertically or horizontally, pan and scroll and invert black and white. All of these also
have an undo option.

The zoom and edit function lets you zero in on a section of the screen and edit it on a
larger scale. Each pixel is blown up to 4 times its normal size. You can then set
individual pixels in any color or draw pixel sized lines in any color. While in this mode
you can pan and scroll to other parts of the screen. This makes working on detailed parts
of the picture much easier. As usual there is an undo option.

Finally, once you have your masterpiece completed, it can be saved so that it can be used
in another program or you can print it directly to a printer if desired. IP has support for
three types of printers plus a facility to use your own external printer driver. Details for
writing a custom driver are supplied. IP can print to Epson compatible 9 and 24 pin
printers and a Hewlett Packard Deskjet 500. The HP driver works in HP mode so you
don't need to use an emulation cartridge. There are options to each type of printer. You
can specify a mono or shaded printout and you have the option of inverting black and

IMAGE PROCESSOR 2 - (CONT’D)

white for printing The Epson type options also let you specify the number of passes of
the printhead per line. The built in drivers are configurable as far as the codes required
by your printer to tell it what type of graphic printing to do.

Image Processor 2 is a very powerful, easy to use program to handle QL screen pictures.
It has a wide range of features and is very user friendly. Buy it.

(Editor's Note: IMAGE PROCESSOR 2 can be obtained directly from DJC (please see
Dilwyn's adverts in this issue) or from any QL dealer worldwide who carries DIC
software.)

NEWS FROM DILWYN JONES COMPUTING

DJC has extented its already wide range of QL software by reaching agreement with
some of the authors of the commercial software formerly published by CGH Services
(CGH stopped trading at the end of March 1993). The following seven programs have
been re-launched by DJC: SQUIDGY ROUND THE WORLD, OPEN GOLF, GREY
WOLF, QUICK MANDELBROT III, SToQL, QUIZ MASTER II and 5 GAME PAC.

In addition to the above DJC has launched a much asked-for utility program to print
wide spreadsheets and text files sideways in landscape print on 9 and 24 pin dot matrix
printers The program is titled SIDEWRITER and the cost is a mere £15.

pl u s4 QL Wordprocessing at its Best

IMPROVING YOUR PRINTING: Option 1

New printers using twenty-four pin, bubblejet, inkjet or laser technologies offer very fast output of the highest quality. They feature multiple proportionalty
spaced founts in different sizes. They allow precision adjustment of spacing between words and between lines.

On the QL, only plus4 with its dedicated printer drivers is capable of utilising these advanced features. We mean utilising, not playing with. We mean the
abitity to calculate automatically the number of words that fit within the margins, justifying with proportionally spaced founts as weil as typewriter style fixed
pitch. And the facility to vary line-spacing in different parts of the text with automatic calculation of page breaks. Plus page layouts with multiple cotumns,
with equat or unequal widths.

plus4 and its printer drivers put all these features at you fingertips. Select the appropriate driver once and forget about control codes, translation of
accented characters, counting the lines to fit the page. calculating the number of characters that fit within the margins--all the tedium that is part and parcel
of wordprocessing with other programs.

IMPROVING YOUR PRINTING: Option 2

You may already own a 9 pin dot-matrix or daisywheel printer. Upgrade it with plus4! We have written forty dedicated printer drivers for those old
favourites. Although not in the same league as far as output quality and speed are concerned, they share some of the features of modern printers. plus4
brings out the best those printers are capable of.

IMPROVING YOUR PRINTING: Option 3

plus4 drivers mentioned so far are text-mode drivers which print at the fastest possible speed: up to several pages per minute with fast printers. We were
not talking about graphic mode printing which is not of the same quality and is hampered by the serial port bottleneck {it can take several minutes per page
even with the Gold Card). Nonetheless, we also offer plus4 users a graphic mode driver for dot-matrix printers: fountext88. Up to 32 bit-mapped founts
can be loaded with fountext88 and used freely in your texts. It typically takes less than 4 minutes to print a full page which is very fast by QL standards
founted89 allows you to modify the founts or design your own

QL GOLD CARD

£225 inc. (£200 outside EC)

This is the expansion that has been revolutionising the QL. It is very easy to fit -
it simply plugs into the expansion port at the left hand of the QL - and once fitted
it will instantly increase the execution speed of the QL by about 4 times due to
the presence of a 16MHz 68000 on board. There is 2M of fast 16 bit RAM of
which QDOS sees a contiguous 1920K. The remainder is used for shadowing
the QL's ROM and display memory and for the GOLD CARD's own code.

There is a disk interface which can access 3 mechanisms (4 with the DISK
ADAPTER) of 3 different densities, DD (double density, 720K), HD (high density.
1.44M) and ED (extra high density, 3.2M) in any mix. The disk interface
connector is the same type that was fitted to the TRUMP CARD so most QL
compatible disk drives can be used. Please note that DD drives still give a
Capacity of 720K per diskette. Our DUAL ED DISK DRIVE allows the GOLD
CARD to access DD. HD and ED diskettes.

Another feature is the battery backed clock. When the QL is switched on the
contents of the clock are copied into the QU's clock so that the time and date are
correct. The firmware in the ROM gives the GOLD CARD ali the functionality of

the TRUMP CARD like TOOLKIT II and there is a sub-directory system for
floppy and RAM disks.

Physically the GOLD CARD is about half the size of the TRUMP CARD and so

fits almost all within the QL. Its current consumption is well under the allowable

Maximum so no special power supply is required. The GOLD CARD comes with
a 14 day money back guarantee and a 2 year warranty

MIRACLE

THE QXL

The QXL turns the common PC into a QL compatible. The package comprises a half
card that plugs into an 8 or 16 bit standard ISA slot and a diskette loaded with a QDOS
compatible operating system and a Superbasic compatible interpreter. After installation
Simply type QXL and the PC will appear to be a QL allowing QL programs to be run from

QL format diskettes.

The card itself has a 32 bit 66EC040 processor running at 20MHz which gives a good
turn of speed. This processor has access to its own RAM and so performance is virtually
independent of the host PC whether it has an 8088 or a Pentium. In fact the PC is used
purely as an I/O system giving QL programs access to the PC's floppy disc, hard disc,
keyboard, display, serial and parallel ports. The card itself has QL style network ports to
allow connection to a QL network. The minimum PC specification required is an XT with
EGA display and a spare standard slot.

Varying RAM sizes from 1M up to 8M can be supplied. The smaller capacities can be
upgraded to the larger ones and the cost is simply the price difference. Not all the RAM
is available to the user programs; the 1M equates roughly with a TRUMP CARD QL
memory size and the 2M with a GOLD CARD QL.

During the lifetime of the QXL we intend to enhance the software to make use of the new
hardware facilities of the PC such as SVGA graphics. As has been our policy with the
TRUMP CARD and GOLD CARD we intend to provide software upgrades free of charge.

QL-2000 TOWER CASE QL DIY-KIT
Troy, Michigan, USA - John J. Impellizzeri & Don Walterman

This kit is from Computer Technik /Jiirgen Falkenberg in Germany and lets you move
your QL into a modern mini-tower case. You gain many advantages from this move: disk
drives in the same cabinet as the computer, room for expansion cards in the same case,
stable power supply, one power switch for the system, smaller footprint and more
modern appearance. There is clearance for a ROM cartridge to be installed, although
you have to partially disassemble the PC case to install or remove it. The kit requires
some serious work on your part. The manual estimates 4 hours for installation. We found
12 hours to be more accurate at least the first time around.

г if M Р Ве prepared to do some serious

; ως soldering. While the instructions
provided basic details for mechanical
mounting of the QL components, some
ingenuity will be helpful in a successful
installation. For example, the basic kit
provides two standoffs to mount the
main board. (These are the two original
mounting holes). While this does work,
it means everytime a chip is replaced or
wa new option is added, the board will
flex. We added 7 additional standoffs
(nylon spacers) underneath the main
board. They were not attached to the
main board but just provided some
(QL with Tower Case and supplied parts) ^ support under the socketed chips.

We also decided to add some improvements along the way. This makes sense since you
bave the QL completely disassembled anyway. You might consider purchasing a spare
QL motherboard. Whole QLs are available in the U.S. for $35. This allows you to spend
time modifying the motherboard properly without preventing you from using your
system (it also provides you with a little safety margin in case you miswire the power
connections). We added the Tom Bent modifications. (If you haven't heard of these
=. . modifications and are interested
q 5 > contact IQLR). The power supply fixes
were not implemented as they are a
» moot point with the new 200 watt
& supply in the mini-tower case. The
„ instructions for converting the power
; supply to drive the QL are good except
that the wire colors supplied didn't
completely match the directions. The
directions were also vague about where
to mount the QL’s original heat sink. A
drawing would have helped. We chose
- to mount it to the bottom mounting lug
of the power supply. This caused
problems later on when two floppy
drives were replaced with a 40 MByte
(modified QL motherboard) hard disk. The hard disk was deeper

15

QL-2000 KIT - (CONT'D)

than the floppies it replaced. The power connector on the hard disk ran into the heat
sink. If we had known this in advance, we would have mounted the heat sink elsewhere.
Since the cables were already cut to length, we used a different shaped heat sink to get
some clearance.

The main problem area was the Bus-Expander. This is a 'flip-over' card that puts your
QL expansion bus cards upside-down over the QL itself. Pay attention to the instructions
on page 3. The Bus-Expander must be connected before installing the QL main board in
the case. There is not enough clearance to install the expander after the QL is mounted
in the case. The board works fine but has some serious mounting and stability problems.
No means is provided to anchor the expander to the QL or the expansion cards to the
expander. Also the expander backplane is within 1/4 inch of bare sheet metal of the case.
The manual recommends using some scotch tape but we didn’t find that an adequate
solution. What’s needed is something insulated to keep the expander board from shorting
against the metal case and also to keep the board firmly seated in to the QL. Once you
get the expander board seated and insulated you are still left with the problem of keeping
any expansion cards plugged into the board securely. Since they hang upside down over
the QL motherboard with no support any vibration could dislodge the board (witha
hard disk you will have some vibration). One possible solution is to tie wrap the DIN
connectors together. Each connector has a mounting hole on each end. These can be tie-
wrapped to the corresponding hole in the backplanes’ DIN connector. That would
prevent the boards from working loose from the backplane as well as provide some
stability. You have to be careful that any expansion boards don’t contact any
modifications such as caps, EPROM boards, QIMI etc, that may be installed on the QL.
Often these add-ons assume this space is vacant We haven’t come up with a good
solution yet but this does need to be addressed. We tried using the Bus-Expander with the
flexible ribbon cable. This can be mounted to the back of the case using standoffs. This
eliminates the chance of shorting out and makes the backplane stable. However, my
Gold Card did not work reliably off this backplane (other boards like the Cumana disk
interface, JFC hard disk interface and Miracle expanderam worked). It appears to be a
seating problem since I can get the Gold Card to work by flexing the connection on the
backplane (this Gold Card is 100% reliable when plugged into a standard QL). A little
more experimenting is needed here.

Another potential problem area is the video extension cable. The DIN 8 connector
makes a hard right angle bend as it exits the QL board. It works fine but it is a very tight
fit. In addition to extra parts listed in the kit instructions, you should add shrink wrap,
heat sink compound, RS-232 standoffs and small hardware to your parts list. Some of the
supplied hardware just did not fit well but that could be the fault of the case
manufacturer. However, the supplied adapter to mount the DB9 connector for the
joysticks doesn't fit well in the DB25 cutout. Standard adapters are available for this
application. (JDR Microdevices supplies a PC bracket with 2 DB9 cutouts for $1.95 each
part number BKT-14. JDR has no minimum order requirements.) We also added an
extension cable for the JFC Keyboard 90 interface (another very tight fit).

We had one defective part to troubleshoot Some of the coax supplied to extend the
network ports to the back of the case was defective. It probably was broken during
installation of the network ports in the rear panel The ports are located very close
together making installation difficult.

16

QL-2000 KIT - (CONT'D)

The new QL-2000 was tested with a Gold Card installed. It worked just as well as a Gold
Card on a standard QL. Now that you have the QL installed in the new case, adding any
extras like Qimi, Minerva or JFC Keyboard is much easier since there is more room and
better access to everything.

The kit does not provide for mounting
the microdrives. The instructions
describe them being available as an
optional extra. It also does not provide
a cutout for the Qimi mouse. You can
sacrifice a joystick port if you choose
or you could use a standard PC
expansion card plate and mount a
connector there (JDR part number
BKT-12 bracket with 1 DB9 cutout).

+ This kit was fun to assemble and
ГА «V. ™ produced a much cleaner QL package.
ЕЕЕ. i ME à w If you are willing to spend some time,
(completed QL-2000 DIY-KIT) do a lot of soldering and a little
problem solving, this is a very
rewarding project. The case now holds 2 floppies, a 40 MByte hard disk, JFC keyboard
interface, JFC hard disk interface, Gold Card, Minerva Mark II and power supply. Try to
put all that in the original QL! If you are interested in the kit but don't want to spend the
time or don't like to solder consider one of Compter Technik's package deals or contact
IQLR. The QL-2000 was on display at 'Miracle in Newport. It generated alot of interest.
A number of people expressed a desire for a version of the QL-2000 that contained
instructions and the necessary parts minus the case itself. This would allow people to take
advantage of whatever local specials they see.

The QL-2000 DIY Kit is available from Computer Technik/Jürgen Falkenberg
07231/81058 phone or 07231/81058 fax, or W. N. Richardson & Co. in the UK, or
Mechanical Affinity in North America. JDR Microdevices can be contacted at (800)
538-5000.

HELPFUL HINT (External Keyboard-90 Interface)
Tiverton, Rhode Island, USA - Dick Taylor

This was an idea that I hadn't considered of interest to anyone until Tony Firshman
commented on it at the "MIRACLE in NEWPORT" show. I have been using Jurgen
Falkenberg's external Keyboard-90 Interface for several years and use a QL keyboard
top that has a blank plate in place of the keys. I cut a slot in the plate for the ribbon cable
connecting the 8049 (now Hermes) chip socket and the Interface box. The problem with
this setup was that the Interface box tended to shift around during use and had a
tendency to work the 8049 chip loose in it's socket. To correct this, I stuck a small piece
of Velcro tape between the plate and the bottom of the Interface box. This not only
corrected the problem, but also allows me to move it aside when opening the QL case.

EASY POINTER II- A Review ALBIN HESSLER SOFTWARE
Thetford, Norfolk, GREAT BRITAIN - W. Geraint Jones

I have of late, as anyone who reads the Quanta magazine knows, been experimenting
with the Pointer Interface, and writing about my experiences to boot. In the middle of
learning and writing about programming under pointer in assembler a package arrived
from the States containing Easy Pointer and a request to review it from that nice chap
from RI you know who I mean.

Easy pointer What is it?

The whole package consists of a very thick manual and three disks, each of which
contains one of the sections of the package. The software consists of a number of
SuperBASIC machine code extentions a number of executable pointer driven programs,
of which Easysprite, Easymenu and Easysource are the main utilities. Also included on
the disks are a number of complete examples of windows, menus and an assortment of
SuperBASIC and assembler pointer program examples along with a number of library
routines.

The purpose of the package is not, as the name implies, to make programming under the
pointer environment EASY, but EASIER, in so far as it allows the user to design the
programs windows and associated menu items in a safe user friendly environment. I say
easier rather than easy, because the hardest part of pointer interface programming is not
designing windows, sprites, loose menu items or standard menu structures, but the code
necessary to execute the options given in the menus.

It is not my intention to take the reader on a step by step 'idiots' guide of the software
and how to use it, but to give the reader a general feel for the package overall and what it
can do for you. To this end the package can be divided into five sections vis:

1) Easysprite

2) Easymenu

3) Easysource

4) the extentions and
5) the manual,

I will for simplicity discuss each section in order.

1) Easysprite

Easysprite is a utility program that allows the user to interactively generate graphic
objects. The program is obviously pointer driven and can operate in either mode 4 or 8.
The graphic objects allowed under the pointer environment can be divided into three
distinct yet related types, these being sprites, blobs, and patterns. All graphic objects are
generated as sprites and may be previewed as either static objects or pointers in the
preview window. The objects developed within Easysprite may be saved as sprites, blobs
or patterns on either an individual or a collection basis. The program also has the ability
to generate dynamic sprites. The sprites, blobs and patterns may either be generated
manually by filling in each pixel or by using the programs ability to extract a section of
the screen from a previously created screen dump. All objects created may also be
rotated in 90 degree steps and moved about the grid pixel by pixel.

The ability to generate files containing collections of sprites, blobs and patterns is

20

EASY POINTER II- (CONT'D)

particularly useful when a number of different items are to be generated in a menu
system. However, it is worth noting that the collection files cannot be loaded back into
Easysprite and as such should also be saved as separate items. It is also worth noting that
due to the nature of blobs and patterns they should also be saved as sprites, thus allowing
them to be recalled for possible future modification.

As I have already said the objects are generated as sprites, but may be saved as either a
sprite, a blob or a pattern. What then is the difference between the three types of objects.

Sprite Object

Sprites are made up of two masks the first mask, called the colour mask, defines the
colour of each individual pixel within the sprite, while the second, pattern mask, defines
the shape of the sprite by defining which pixels within the sprite are visible.

Blob Object

Blobs are made up of only one mask, this is the pattern mask and only defines the shape
of the object. As such in order for a blob to be visible it must be combined with a pattern.
The pattern to be combined with the blob must of coarse be defined separately.

Pattern Object

Patterns like blobs are made up of only one mask, in this case the colour mask which
defines the colour of all pixels within the pattern. Again in order for a pattern to be
visible it must have a blob to combine with, which is of coarse defined separately.

Combining Blobs and Patterns

When a blob is combined with a pattern a visible graphics object is created eg combining
a circle blob with a red pattern results in a red circle. Since a blob can be combined with
different patterns it is possible to display the same shape in a number of different
colours, and conversely a single pattern can be combined with different blobs, thus
enabling the shape of a graphics object to change.

Overall Impression

My overall impression of this program is that it is a very well thought out and useful
development tool, the ability to extract sections of screen images is an especially useful
facility. The functions of the program are covered in the manual, the only drawback
being a lack of worked examples, especially on the use and storage of more than one
object in the programs working area.

2) Easymenu

This program is pointer driven utility that allows the user to generate their programs
front end window, including loose menu items, information subwindows, application
subwindows and pulldown menus interactively. The program only generates the
information required to define the window, it does not generate any of the code
necessary to set up, use or manipulate any of the menu structures this is left to the user
via either his/her own assembler code or the supplied SuperBASIC extensions. While all
the graphics objects have to be generated externally, the layout of information objects,
loose menu items and the colour schemes associated with their current status are set up
within Easymenu. The program also allows the user to generate the necessary data
structures to create both static and dynamic text menus, but not to control them, this

21

EASY POINTER III - (CONT'D)

again is down to the user. What I have already said about the primary window also
applies to secondary windows used as pulldown menus by loose menu items etc.

Overall Impression

While the program is once again well thought out and a very useful utility, the same
cannot be said of corresponding section of the manual. It is somewhat unfortunate that
the manual only describes the commands available to the user, but not how to use them
to generate a window with its associated menu items etc. The program is good but
requires an inordinately high level of input by the user before any useful output can be
produced. The effort required to use this program could, and I believe should, be
reduced by the inclusion of a few extra pages in the manual describing in order the
operations required to produce an example window.

3) Easysource

This program is very much for the assembler programmer, as its soul purpose is to
dissassembie the binary code produced by Easymenu to generate standard assembler
code. The beauty of this program is that the assembler code produced is very well
commented and easily assimilated into the users code.

Overall Impression

This piece of software is the one that makes the package attractive to the assembler
programmer, as it enables the other programs to act as a proper development tool for the
program front end, markedly reducing the amount of code the programmer has to type
and debug.

4) The extensions

These are a series of SuperBASIC procedures and functions, written in machine code,
that enable the user to write pointer driven software in SuperBASIC. This has of coarse
already been done in the Pointer Toolkit, so is this a case of re-inventing the wheel. No,
its not, the purpose of these extensions is to allow the user to manipulate the menus etc.
produced by Easymenu and the pointer interface in general at a lower level than can be
achieved from the Pointer Toolkit. This is achieved by allowing the user direct access to
the Trap and Vector calls used by the assembler programmer, directly from
SuperBASIC, thus giving the user the same power as the assembler programmer from the
comparative safety of SuperBASIC.

5) The Manual

The manual supplied is not unfortunately what I would call a true manual, but a
reference source. I say this because my idea of a manual is a set of instructions that not
only tells the user how the software works, but also shows the user how to use the
software in easy to follow steps. The manual consists of three main sections, covering
Easysprite Easymenu the SuperBASIC interface, Easysource and the use of the data
structures generated by both the assembler and C programmers. While, as stated above, it
details the commands available to the user in the various software packages and the
SuperBASIC interface, it does not in my opinion go far enough in demonstrating to the
user how to use the software to generate pointer driven programs. There are plenty
of examples of what can be produced using this package on the disks supplied, but these
are finished examples, not worked examples and the manual does not show how to
generate them, but merely states that they exist.

22

EASY POINTER III - (CONT'D)

Conclusion

The package is well thought out and well designed and to my mind makes the
development of the user interface easier by allowing its appearance to be designed
interactively thus doing away with what would normally be a great deal of typing in any
language. The manual could be improved by including worked examples and explaining
exactly what is going on. The manual aside Easy pointer is a package that is of use to
anyone who is interested in pointer programming, at whatever level.

OMATHS I - A REVIEW: Part 2 of 2 DIGITAL PRECISION LTD.
Oak Ridge, Tennessee, USA - Mel LaVerne

In Part 1 of this Review, I covered Qmaths and Qfract. In this final portion, 1 propose to
discuss the Surface Modeller, High Precision Calculator, and Mathematical
Compendium, the last being a sort of mish-mash of items that may not have fit neatly
into a previous category.

SURFACE MODELLER

This program depicts the 3-dimensional surface defined by the equation z = f(x,y) over a
rectangular grid [x1,x2] by [yl,y2] Fineness of definition is determined by the user
selected number of intervals in the x and y directions. The surface is computed only for
the selected points and linearly interpolated between points.

To visualize the surface, imagine a sphere having the above grid in its equatorial plane.
Further imagine a second plane tangent to the sphere at some latitude and longitude (the
viewing angles). Now project the surface defined by f(x,y) orthogonally onto this second
plane. This yields the surface as drawn on the screen.

User input consists of the function f(x,y), the grid size, numbers of intervals in the grid,
two viewing angles, a scaling mode, and a presentation mode.

For the scaling mode you are offered three options: 1) No scaling, i.e., the surface is
plotted as is; 2) Automatic rescaling; and 3) Scaling of the z-axis.

There are 9 presentation modes, 0 to 8. The choices range from the usual 'wire-frame'
with all lines visible to lines drawn only in the y-direction or x-direction to hidden line
elimination in black and white to hidden line elimination with color.

I find modes 2, 5, and 8 the most attractive (spectacular, even). All three modes are in
color, upper surfaces being filled green and lower surfaces, filled red. Hidden lines
and surfaces are suppressed. The modes differ only in the sets of lines drawn on the
surfaces: mode 2 draws both the constant x and constant y lines; mode 5 draws lines only
for constant y; mode 8, only for constant x.

Modes 1, 4, and 7 are similar to the above, except for lack of color. Finally, modes 0, 3,
and 6 are like 1, 4, and 7, except that hidden lines are not suppressed ("wire-frames").

23

QMATHSI Part 2 - (CONT'D)

In general, I find that "Surface Modeller" is easy to use and gives an excellent
presentation. Resolution is limited only by the imposed maximum of 40 intervals in
either direction (discovered quite by accident; no limit is mentioned in the manual).

Having said all that, I must admit to a few caveats. What the program does is not always
what the instructions say will occur.

For instance, we are told that, when the surface has been drawn, pressing F3 will allow
changing the view angles. Not so! Pressing F3 causes the prompt “Archiva donde salvar
-->" to appear (all prompts are in Spanish; more on that later) and the program waits for
a response. I interpret that to be a request for a file name for saving the picture.
Supplying a name then engenders a further prompt, "Con Datos ? (s/n)" ("with data ",
perhaps ?).

The instructions say that if your inputs "generate something impossible", you will get an
error message and be allowed to re-edit the input. Not always. For example, I set the
viewing angle theta equal to zero in the default function. This appears to be
unacceptable and I did get an error message ("Error en linea 1760"). However, the
program stubbornly refused to allow editing the offending theta, cycling through the first
line of input only (theta, of course, is in the second line). I was able to recover only with
a reset.

Finally, with respect to the prompts: the manual blithely says "it is all self evident". I
disagree.

HIGH PRECISION CALCULATOR

This section contains six programs with precisions ranging from 14 to 611 decimal digits,
specifically 14, 33, 72, 149, 303, and 611. Why would anyone want (or need) such
accuracy ? Well, I can think of several reasons.

Some numerical computing schemes require accuracy substantially exceeding the QL's
not quite 9 digit precision. One or more of the first three programs would do quite well
here in reducing roundoff error.

Public key cryptography depends for its security on the ability to handle integers in the
200 to 400 (or more) digit range.

Finally, consider poor William Shanks. In a pre-computer era, he labored for more than
twenty years, with paper and pencil, to compute Pi to 707 decimal places. Unfortunately
for him, somewhere around the 528th decimal place he made an arithmetical error,
invalidating all subsequent calculations. Using PRECISIONGI1, you can surpass his
efforts, calculating Pi to 611 digits in a little more than two minutes. What a feeling of
power !

The programs use Reverse Polish Notation, generally referred to as RPN. Anyone who
has used Hewlett-Packard calculators is already familiar with the system. RPN is also
known as parenthesis-free or postfix notation. "Postfix" simply refers to the fact that an
operation is fixed after (post) its operands. All the programs use a Last In First Out or
LIFO stack for calculation.

24

QMATHSI Part 2 - (CONT'D)

To illustrate the basic system of operation, consider the multiplication of two numbers,
say 5 and 9. In the common infix notation (the operator is fixed in between the
operands), this is written 5*9. In RPN, we would write 59 *. The stack operations would
be: 5 is pushed on the Top of Stack (TOS); 9 is pushed on TOS and in turn pushes the 5
down to Next on Stack (NOS). Next, the operator * is encountered. NOS and TOS are
extracted from the stack, the operation performed between them and the result, 45,
placed back on TOS.

Illustration of the basic operation is all very well, but how does one check the correctness
of a 611 digit product ? Just producing a 305 digit multiplicand and a 306 digit multiplier
could be a major undertaking, let alone verifying correctness of their product.
Fortunately, there is a way out. The quantity JO^n - 1 is a series of nines, n digits long
and the product of two ch numbers is easily determined. Hence, we simply use, for
the multiplicand, 10^305 - 1 and for the multiplier, 10^306 - 1. The input expression
to PRECISION611 is then: 10305 ^ 1 - 10306 ^ 1- *. The product is easily verified to
consist of 304 nines, followed by the number 89, followed by 304 zeroes, and terminated
with a single one, for a total of 611 digits.

A 610 digit product is even easier: square the quantity 10^305 - 1, as follows: input the
expression 10 305 ^ 1 - dup *. The only new item is "dup", a FORTH word meaning
duplicate TOS. As a result, 10°305 - 1 is in both TOS and NOS so that when the * is
encountered, we obtain the square. The number is like the above 611 digit number,
except that 89 is replaced by 8.

The above procedure, with appropriate values of n, was used with each of the
PRECISIONxxx programs to verify correctness. Each passed with flying colors. I
recognize that this may not be proof positive that the programs can correctly handle all
results of up to 611 digits but I’m satisfied.

The programs are obviously not limited to simple multiplications but can be used with a
host of different operators, trigonometric, algebraic, exponential and others. The
manual lists 47 operators in all.

The manual also includes a number of worked out examples and an illustration of setting
up an iteration.

MATHEMATICAL COMPENDIUM

This section appears to have been written by a number of authors who spoke neither to
each other nor to the author of these instructions. For instance, the Introduction states
"We have deliberately not used the finer features of SuperBASIC (REPeat, ...".
However, I find that, eg, "SQR PATTERN" uses REPeat..END REPeat and
"QUICKSORT" uses PROCedure, REPeat, LOCal, etc. This hardly "ensures that the
routines can be typed into humble machines (PCs)...".

Some of the problems I have encountered in the "Compendium" follow.

"SPEED ACCUR" claims five accuracy tests. However, test 3 never appears; a heading
is printed but nothing happens. We then move on to tests 4 and 5.

25

QMATHSI Part 2 - (CONT'D)

"COLLATZ HYP" cannot run as written (except for n = 2 or 3). The problem is in line
155, which reads: 155 IF N<>N*INT(N/2) THEN GO TO 150. The solution, of course,
is simply to delete line 155. But why was it there in the first place ?

"FACTORS" claims that an error message will appear if a negative number is input. Not
80; the program simply ignores the input and asks for another number. Incidentally, "just
deserts" should be "just desserts" !

"EASTER DAY" fails for any odd numbered year. Again, the problem is a bad test.
The condition "Y<>2*INT(Y/2)" occurs in line 150. Since this is true for any odd Y, the
program returns to the input line. The cure here is to change the condition to
Y<>INT(Y), which has the side benefit of error-trapping non-integer input.

"STATISTICS", if asked for mean and variance, says it returns the mean and standard
deviation. Unfortunately, variance and standard deviation are different quantities.

"SIMPLEX" cautions against entering negative or non-integer values, because "all hell
will break loose." I tried some illegal non-integer values; the program quite calmly
processed the data with no problem. In fact, the results differed little from those for the
proper integral input !

"FITANDPLOT" declares that selecting more terms than the number of data points will
(a) make the system over-determined and (b) give an error message. (a) is true enough
but (b) does not happen. I must admit, though, that the resulting polynomial is worthless
as a representation of the data !

I find the plots for "HITANDPLOT" and "FIT EXP" to be of little or no value, primarily
because of the lack of any scales on the coordinates.

It might appear from the foregoing that I consider the Compendium to be of little value.
Not so; I found the sections "SORTING" through "LINEAR SYSTEMS" to be quite
useful, as well as some parts of "ITERATION". "NUMERICAL INTEGRATION" was
of especial interest (personal preference, perhaps ?), the section on Romberg's method,
in particular.

I have checked "ROMBERG METHOD" to some extent by integrating dx /x from 1 to 2.
This should yield In 2. I obtained 0.6931472 as a result As a check, I used
"PRECISIONOI4" to get the 14-digit result 0.69314718955994, which rounds to 7 decimal
places as 0.6931472, an excellent check.

The instructions for "ROMBERG METHOD" give the impression that Romberg's
method of integration simply involves repeated trapezoidal (note: US usage; ’trapezial’
in UK usage) integration, doubling the number of intervals each time. Actually, there is
considerably more to the process. For anyone interested in what is actually going on, |
suggest perusing a book on numerical methods, such as "Applied Numerical Methods" by
Carnahan, Luther, & Wilkes, page 90 et seq.

On return home from “Miracle in Newport" (If you weren’t there, you should have been
!), I found that QL World also had a review on QMATHS. If you have access to a copy

26

QMATHSI Part2- (CONT'D)

of QLW, you might be interested in another slant on the same subject. I was puzzled by
the reviewer's reference to OMATHS Part Two"; my disk says it is Part One.

Since submitting Part One of this review, I have been playing about with Qmaths and
have come across a curious result in the manipulation of complex quantities. The Help
file on factoring says, in part, "Complex: will factorize into real and imaginary parts".
One would expect, then, that the sequence Transform; Expand; Transform; Factor;
Complex would yield a final result properly separated into real and imaginary parts.
Well, maybe.

I have so far tried factoring (a +b*i) ^п for n = 2 to 10 (Note that the expression for n =
1 is already in proper form). The "curious result" is that for n = 2,4,6,8,10, the expression
is properly separated. But, for odd n (3,5,7,9), the procedure fails ! For instance,
(a--b*i)^2 transforms to a^2 - b^2 + 2*a*b*i, asit should. But, (a+b*i)*3 transforms
to -b^3*i - 3*[a*b^2 - b*a^2*i] + a^3, correct in its way, but not properly separated.

(Editor's Note: You can read the first part of this review in our previous issue (Vol. 3,
Issue 1). In the near future look for Mel to review QMATHS II. QMATHS I and II are
available from DIGITAL PRECISION LTD, please see their adverts elsewhere in this
issue.)

RDS (Random Dot Stereograms)
Wilmington, Delaware, USA - Herb Schaaf

Somewhere in this issue of IQLR there should be a page with lots of dots on it; dots that
seem to be arandom pattern, with a pair of small hollow boxes along one edge.

If you change your focus while looking at a RDS and allow the image processing
computer in your brain to take over, a three-dimensional effect will be seen.

Programs to generate RDS on your QL should also be somewhere in this issue. One
program is in SuperBasic and should run on any QL. Another is source code in C that
worked with the C-68 compiler version 1.05. I've tried to make both programs have
about the same “look and feel’ and you might enjoy comparing SuperBasic with C. If the
REMarks and * /comments/* are more verbose than you like just leave them out. If you
want to save screens in the SuperBasic version change lines 950 and 960 to suit your
system. There is stuff in the C program that you might want to chuck out if PBM, UNIX,
X-terminals etc. aren't of interest to you.

Some people may not be able to 'see' the RDS effect due to the way their eyes work or
because of vision problems. A quick test of your vision is to touch the tips of your index
fingers so they are pointing to each other, then hold them out at arms length in front of
you and look through them, focusing on a distant wall or the far horizon. Now spread
your arms slightly so that a 1/4" gap exists between your fingertips. Focus on the wall or
horizon and look for the illusion of a ‘little sausage’ floating in between your two
fingertips.

left hand right hand |

If you 'see' the little sausage then you should be able to see the RDS effect as well.

The 2 hollow boxes on the RDS are guides to help you get the proper de-focusing and
alignment. They are placed at the bottom edge and will 'appear' as 3 or 4 when you look
"beyond" or "half-way to’ the RDS. Make sure they are all in a line by tilting the RDS,
your head, or both. This is critical for most (but not all!) people. If you 'see' 4 guide
boxes, change your focus somehow so that the 2 in the middle merge into 1; then there
will be only 3 guide boxes. When you 'see' 3 guide boxes then lock-on to the center one
“ло ΠΑΘΗ take in the RDS, verifying from time to time that the center guide box is
still clear.

In QHJ #9 (QL Hacker's Journal June 1992) there was a article by me about RDS on
pages 5 to 11 that included several other 'shapes' to try. QHJ is distributed over the
Internet, so my write-up was picked up, passed around, and part of it was in QUANTA of
January 1993 on pages 22 to 25.

The version here is an 'improvement' to my first algorithm as 1 am afflicted with
"Babbage's ailment"; thus I tweak the code, modify the design, and ‘еер on adding
creatures’. As mentioned in the original QHJ, I am especially proud of my 'Escher knot’.
Let the editor know if you are interested and I can describe some of the complicated
ways I found of doing it. With lots of memory such as Trump card or Gold Card I can
show the Escher knot spinning, revolving, tumbling in 3-space. I’ve even got two in
motion in the same space at the same time, a red one rotating on the Y axis and a green
one revolving about the X axis (or is it red on X and green on Y ?).

Try RDS on your QL and share your interesting ideas with the rest of us. 1 welcome any
thoughts you may have to enhance, improve, clarify, embellish, modify, etc. the
programs. I might have "forgotten what I was doing’ but if there are questions as to why I
did what I did the way I did ГІ try to reconstruct the crofty crime for you.

For those who are on the Internet you may want to read the newsgroup alt.3d where they
call these things SIRDS or Single Image Random Dot Stereograms.

HELPFUL HINT

On a trip to the local hardware store I picked up a roll of 2" wide CLEAR packaging
tape, on the attached card came a list of different uses for the tape including one that
suggested using it to protect shipping labels. You guessed it, before peeling the labels off
the protective backing, I place the clear 2" tape over the printed area and then trim off
the excess tape. Besides keeping my labels clean, it makes it easier to place the label on
the disk, because it keeps it flat, no more wrinkles.

SERMouse (Ver. 3.01) - A REVIEW ALBIN HESSLER SOFTWARE
Shelby Township, Michigan, USA - John J. Impellizzeri

SERMouse is a software driver that allows you to connect a PC type serial mouse to one
of the QL’s serial ports. No disassembly of the QL is necessary. The mouse can then be
used to control the pointer if you’re using the pointer environment allowing much easier
and faster control than the cursor keys. The mouse can also emulate the cursor keys for
programs that don’t use the pointer environment, and will also work if you don't use the
pointer environment at all, the mouse then mimics the cursor keys.

In order to connect a PC type serial mouse to the QL you must make or otherwise obtain
a simple adapter cable. Most serial mice use a female 9 or 25 pin sub-D connector and
the QL will have either a 6 pin connector (UK) or a sub-D9 type. Even if you have a 9
pin mouse and a QL with 9 pin serial ports you cannot simply use a straight through
adapter as the pinouts are different. Instructions are given on how to wire the cable,
although they can be confusing at first glance. Study them carefully and make sure you
use the proper diagram pertaining to your mouse and QL connector types. If you are
handy with a soldering iron and wire tracing you could also replace the connector on the
mouse and rewire it so it would plug directly into the QL.

Getting the right type of mouse is also important. SERMouse was designed for a 3
button PC serial mouse. It will also work with a 2 button serial mouse. You can usually
find these quite inexpensively (under $20) at local computer shows and stores. Some of
these mice will have a switch to allow them to work in two types of modes for the PC.
This switch should be in the PC or Mouse Systems mode rather than Microsoft mode.
Other mice have this same switching done by software. Try and avoid these types,
although the instructions do give some alternative wiring hints that may get them
working. I definitely wouldn't spend a lot of money for some 'super' mouse. Since every
mouse requires power from its host computer there is the possibility that some will draw
more current than the QL’s port can provide. The first mouse I tried ($15) would only
work after it and the QL had been powered up for a while and occasionally would stop
working. I tried a second mouse ($10) and it works great all the time.

Fortunately the hardware side is the hardest part. The software is quite easy to use.
Simply LRESPR or EX the code (or the equivalent if you don't have TK2). The driver
can be loaded either way. If you LRESPR it, you will have some new extensions to
SuperBASIC to control the mouse driver. If you start it as a job (EX) then the
commands are not available but you can control the job like any other in QDOS. The
SuperBASIC extensions allow you to set the mode (pointer or cursor), set the speed of
the mouse (how fast the pointer moves in relation to how you move the mouse), and
reset, suspend, enable and remove the driver. There is also a screen blanker provided.
While these are quite common on most computers including the QL, most will not turn
the screen back on if the mouse is moved. The included blanker will turn the screen on if
any key is pressed or the mouse is moved.

The mouse driver's default parameters can be changed using the standard pointer
environment Config program. | would recommend not changing anything other than
what port you are using until you get the mouse working correctly. After using it for a
while you get a better feel for how fast or slow you want the mouse and what function
the mouse buttons provide. There have been some comments in the QL press on using
the proper driver depending on what type of serial connectors your QL has. There are

38

SERMouse - (CONT'D)

English and German versions of the driver provided. My experimentation has shown
that the driver does not matter. There appears to be no difference other than when you
are using the configuration program. The prompts will be either in English or German.
Both versions seem to work Just fine on my USA QL. (Other than I can't understand the
prompts in the German version).

SERMouse contains automatic support for the Hermes replacement IPC if you have it.
The manual tells you how to configure the driver if you have Hermes. When the driver
loads it will detect Hermes and set only the input baud rate of the port the mouse is
using. Anything that changes the system baud rate will not affect the mouse. If you don’t
have Hermes, SERMouse still tries to allow you to use both serial ports. It remembers
the baud rate before it initializes and then sets it to 1200 for the mouse. If a program
opens a channel to the other port the mouse driver will suspend itself and set the baud
rate back to the previous setting allowing you to use a printer, etc. When the channel is
closed the mouse driver will enable itself again. The manual explains what to do with
programs that don't close the channel right away. Hermes is highly recommended for use
with SERMouse.

SERMouse is a great addition to the pointer environment and is even better with
Hermes. It also works well with or without a Gold Card. Its only possible drawback is
that it does take up one serial port, although an advantage is you do not have to open the
QL case to install it like an internal mouse. Depending on how many serial devices you
want to hook up to the QL’s ports you might be able to use a serial cable switchbox. This
is what I currently use.

My printer and modem share SERI through a switch and the mouse has SER2. Since the
mouse is really only using the input of one port, the output should be free. However
SERMouse uses the unused output line as a negative voltage source for the mouse.
(Mice require +5v, -5v, ground, and data). You could externally power the mouse or
even use the QL’s -12v supply but there is still the problem of the software. Even with
Hermes and Minerva allowing split input and output baud rates the driver opens the
port for the mouse and any other program will get an 'in use' error if it tries to use the
port 1 would like to see a way of having a printer and mouse share one serial port if
possible. With a printer only receiving data and a mouse only sending data it should be
possible at least as far as the hardware goes. Whether or not QDOS will allow it remains
to be seen.

SERMouse can be obtained direct from Albin Hessler or from various QL dealers
including Jochen Merz Software, W.N. Richardson & Co. (EEC) and Mechanical
Affinity.

The mouse I currently use has the following information on it: Keen Mouse, FCC ID:
HQXKEM-260, Model No: KEM-260. I have seen this same ID and model on other
mice that look just like this one. The only difference was the brand name. The mouse
that gave me some trouble was an Identity Systems Technology Inc. IDMOUSE-C, FCC
ID: IOWCM-290.

QSpread is completely mouse- and/or keyboard—controllable and uses, of
course, the Menu Extension. Windows may be enlarged up to the maximum
screen area (think of QVME), the application window may be split in up to
three different horizontal and vertical sections, giving 9 independent control-
lable areas. £very cell may be formatted independently, with many options
(justification, decimal point etc.) and with preview. The monetary symbol may
be longer than one character, e.g. DM. Sum- and other often-used
macro-functions. The size of the sheet is only limited by memory (16000
cells need about 400kBytes). Block handling and block entry is very easy and
useful, especially if you have a numerical pad: you select the block and enter
the values one ofter the other. They are automatically place in the right or-
der. No cursor-key-action necessary! New: celiname-enquiry, echo-func-
tion, different rounding methods. Many additional functions, which belong to
today's standard-equipment: Help, Button-function, use of the Scrap, oll
standard file operations, calculation order row or columns etc. [V1.16j

PERFECTION SPECIAL EDITION... The discoveries began to trip over themselves as
PERFECTION SE responded to the keyboard with unexpected speed and
intelligence... PERFECTION SE is blindingly fast at most things, and you are never
left waiting for tt. PERFECTION is everything that Quil never became: easy to use,
very flexible, loaded with genuinely useful features, cleanly multi-tasking, capacious

“When my ideal finaly arrived in the form of PROFESSIONAL
PUBLISHER, tt surpassed all my expectations... PROFESSIONAL PUBLISHER (is) in
a class of its own, and makes it the only QL desktop publishing program for the very
serious user... Until Digital Precision released PROFESSIONAL PUBLISHER, my
opinion was that the use I could make of desktop publishing was mainly restricted to
short documents... PROFESSIONAL PUBLISHER is a very versatile program... The
illustrations for this series of articles have all been produced on PROFESSIONAL
PUBLISHER... My printer is a BROTHER 9-pin dot matrix printer. It does illustrate
the very high quality that can be obtained from PROFESSIONAL PUBLISHER even
when using a simple printer.” > SINCLAIR QL WORLD magazine Guide to desktop

“Digital Precision (DP) decided to begin work on a replacement for Quill which
would be very quick, simple to use and contain lots of excellent features - something
upon which DP have built a very strong reputation in the QL market... Overall, the
speed-up (of just the first release of PERFECTION - it is much faster now] on even a

Á This URS but a casual sclection, drawing only on extracts from letters
received by DIGITAL PRECISION in the last few days and from articles (in
respected, independent QL journals) that just happened to be to hand. If we
really had to, we could locate. about 1,100 equally complimentary recent
communications (the figure has been carefully arrived at by sampling all our
correspondence files): pleasant though such a trawl would be, we have more
pressing things to do, like keep refining our programs! In case any scepticism
still exists, we refer potential purchasers of our products to pages 18 and 19 of
the September 1988 issuc of Sinclair QL World, which contained three to four
hundred other unsolicited quotations from happy Digital Precision customers
(together with the customer's name and whereabouts), all of whom had bought
their DP programs. That collection covered only three programs (and only partly
- we ran out of space) and predated our best software (LIGHTNING SE,
PERFECTION (+SE), PROFESSIONAL PUBLISHER, PC CONQUEROR
(+SE) etc). We reproduce those pages below, duly reduced to fit (no magnifying
lens supplied, nor eyesight lawsuits solicited). Don't think DP hides behind
small print: send an SAE for a full-size co k fc free while ordering!

SPECIAL DEALS

Buy any two of our programs, deduct 5% from the

total; 10% off 3; 15% off 4; 20% off 5; BE% off 5+!

VERY SPECIAL DEALS FOR IOLR READERS:
Deduct an additional TWENTY PERCENT (20%)
from your order - and this can be combined with
the Special Deals! You've never had it so good! For
example, say you order (together with five other
items) GAMES COMPENDIUM. Ordered individually,
the games would cost 5x£9.95-£49.75. But to you
the cost would be just £29.95-25%-20%=£17.97, a
reduction of £31.78 - a saving of nearly two-
thirds!! And of course you would get both the 25%
and the 20% discounts on all the other five items
too! This offer is open for four weeks from
publication of this issue. Take advantage of this
offer, and of the still ‘cheap’ £ sterling, by acting NOW.

DEMO VERSION OF PERFECTION SPECIAL EDITION!
We have prepared a DEMO version of PERFECTION SPECIAL
EDITION word processor. All saving, exporting, printing,
automatic (manual is OK) reformatting, dictionary-maintaining
and spelichecking (whether by block, page, document or disk)
are disabled or slugged, and speed is somewhat reduced (it is
still very very fast). But absolutely everything clse works. If
you have any doubts as to whether PERFECTION SPECIAL
EDITION can be as good as the ads say, this DEMO version will
soon convince you! To really see this program fly you need large
files, so we supply as part of the DEMO version over 3 megabytes
of absolutely fascinating files, together with ARC, an excellent
p.d. compressor/decompressor for any file. The supplied files
include much of the Bible, Perfection manuals, the Maastricht
treaty, a cleverly scrambled (because of confidentiality) but still
hugely entertaining extract from our huge customer database
and much more. When, having tried the DEMO, you order the
full SPECIAL EDITION (with or without spelichecker), return
disk #1 to get £10 off. The data files etc are yours to keep, of
course. If you own PERFECTION SPECIAL EDITION already, you
can buy just the data files (+ ARC supplied free) for £9.95. We
use the program as a word processor, database, technical editor,
cross-referencing aid, comparator, programming assistant etc.
